IMPRovnDAUTOMATIc FAN.

The Schedule referred to in these Letters Patent and making part ofthesame To all Iwhom it may concern Be it known that I, JOHN NAUGLE, ofMooresville, of Morgan county, in the State of Indiana, have -invented anew and useful Improvement in Automatic Fans; and I do hereby declarethat the following is a full and exact description thereof', referencebeing had to the accompanying drawings, and letters of reference markedthereon.

The nature of my invention consists in a novel mode of producing anoscillating motion, which is communicated to a spindle, to which anumber of fans is radially fastened, in such manner that they may bereadily adjusted to any desired inclination with the said spindle,motion being imparted by a right and a left-handed clock-movement.

In the drawings- Figure I represents a front elevation of my machine.Figure 2 represents a side elevation, showing the fan-head and alongitudinal section of its adjustable socket.

Figure 3 represents a top view, the top being re-l moved, to expose theinner mechanism.

Figure 4 represents a detached view of the reversegearing.

Figure 5 represents the parts by which the sway of the oscillations isregulated.

Figure 6 is a top view of the fan-head.

Figure 7 is atop View ofthe driving-clutches, shown in elevation infigs. l, 2, 4.

Corresponding letters represent corresponding parts in the severalfigures.

To enable others skilled inthe art to make and use my invention, I willproceed to describe its construction and operation.

My machine consists of a mechanism for right and left-handed motion, areverse-gearing and adjustingarrangement, hereafter to be described, allenclosed in a frame, which is made of two plates, A A', connected by anumber of studs, a a a a2, secured together in the same manner as aclock-frame.

Between these plates are a spindle, B, with a gearwheel, b, pawl b2, andratchet-wheel b*, and a spindle,

B', with gear-wheel b, pawl b, and ratchet-wheel b5.

A spring, 117, attached to wheel b, imparts left-handed motion to it,and also to wheel b.

A spring, b5, attached to wheel b5, imparts `righthanded motion to it,and also to wheel l).

A square head, b, on shaft B, and a square head, b9, on shaft B', arefor the purpose of winding up.

The driving-wheel b gears into a pinion, e, on a shaft, C, andto thisshaft are attached a gear-wheel, c2, and a stop-wheel, c, which latteris provided with a number of projections, c6, at its periphery.

In the same manner, the shaft 0 has a pinion, c, a gear-wheel, c3, and astop-wheel, c", with projections c7, of the same size and constructionas the corresponding parts on shaft C, the only difference being thatwheels c3 and c" are fastened at lower levels to their respective shaftsthan wheels cZ and c.

The wheel c2 gears into a pinion, d, which is loose on a shaft, D, andis prevented from sliding up and downl by a pin, d'2, above it, and aclutch-arrangement below.

Likewise, wheel c gears into a pinion, d, on shaft D, which may freelyturn around, but is kept in position by a pin, d3, below, and theclutch-arrangement above.

rlhe clutch arrangement consists of two clutchplates, E and FF, and atube, E, between them, which tube is fastened to the shaft D, andprovided with a rib, or feather', e2.

A double clutch-plate, F, is so fitted on the tube E that it ma'y slideup and down on it. The clutch El is fastened to the pinion d, and theclutch E2 is fastened to the pinion d.

.In iig. 2, the double clutch F is represented in gear with the upperclutch, E, and, in iig. 4, it is represented in gear with the lowerclutch, E2. In the first case, the shaft D receives motion from wheel b,which is a righthanded one, and, in the latter case, the motion isreceived from wheel 11S-and is a left-handed one.

The pinion d1, with its disengaged clutch E2, as seen in lig. 2, wouldrevolve with great rapidity and loss of power were it not for a doublesliding check, G, which, with one of its projecting laps y, stops thefurther progress of one of the projections o6 on wheel c", therebyystopping the whole right-handed movement.

.A lap, g, on the other side of the check G, is, at the same time, belowthe level of wheel o5, whereby one of v its projections, c7, ispermitted `to pass, Which causes the shaft D to be' revolved toward theleft-hand from the wheel b1.

Fig. 5 represents the check G in full, and the stop wheels c4 c5 insection, in such position as to cause a left-handed-motion, or revohtionof shaftD.

To make the check G slide up and down, I couple it with the slidingclutch, F, by means of a strap, F', which encircles an annular groove onsaid clutch.

The one joint f ofthe strap F is fastened to the end of the check G,while the other joint, f is fastened to a connecting-bar, h, which isagain fastened to a sliding head, H,.at h1.

The check G is also fastened to the head, H, at h2, and aconnecting-bar, h3, fastened to H, and jointed to the short arm of auelbow-lever, I, transmits a vertical motion to the head, H.

The longer arm of lever I receives its motion, at its end, il, from twopins i? and i3, ywhich are fastened to the shaft D, and strike and movethe said lever-arm alternately, according. to the oscillations of theshaft.

As the head, H, strap F, and check Gr, are rigidly connected, and as aforked bearing, g2, fastened to the check G, and sliding on a verticalguide, a3, projecting from stud a2, permits a vertical motion, it isevident that the mot-ion of the three parts H F' G combined, is only avertical one, while E, pal-taking of the same motion, is also permittedto oscillate in the encircling strap.

It is understood that the sliding clutch is alternately changing itsmotion as it is either moved up or down and brought in contact withclutch E or with clutch E.

The shaft D projects through the upper plate, A', of the frame-work, andanother shaft, K, supporting a fan-head, is Afitted with its socket-endk to this projection, to which it may be fastened, at any height, by aset-screw, It', as represented in section in fig. 2.

The fan-head consists of a number of arms, fastened to shaft K, by whichthe fan-sockets are supported. There are four such arms, two of whichare only seen in the drawing, lk2 and l.

The connection of the arms and fan-sockets is shown in fig. 2, in whichone arm, k, is shown supporting, with a joint, l, a socket, l2, with arod, Z, fastened to it.

As the socket is overbalanced at its outward end, the

`rod ll is pressed against the lower part of a pressurehead, L, which iskept in position by a set-screw, L', screwing into the top of shaft K.

If I screw L down, the head, L, partaking of the same motion, depressesthe rod, l, and thereby tilts the socket l2, and lifts the fan, whichmay he inserted in the socket, and cioe versa.A This may be done to anydesired height, owing to the peculiar shape of rod l. It can also bedone while the machine is in operation.

The fans, or brushes to be inserted in the sockets Z2 l3 l Z5, may be ofany known construction, size, or material, and, as they are movable, Imay, at convenience, use one, two, three, or four fans at the same time.

The machine makes a half revolution at cach stroke. I' prefer a quarterrevolution, as suitable for the greatest variety of purposes. If it isdesirable to have a mach-ine with adjustable stroke for any fraction ofa revolution, the projections c, on wheel ci, and c7, on `wheel c", mayhe made removable, and thus fasten a larger or smaller number of them tothe wheels c* and l which the machine may berstarted or stopped atpleasure after it is wound up.

Having thus clearly and fully described the construction of my machine,I proceed to describe the operation of it.

After winding up the springs bs and b, the wheel c", beingdisengagedfrom the check G,'moves the shaft D to the left until the pin i3 strikesthe lever-end i, and thereby lifts the clutch F, disconnects it from theclutch Ez, and connects it with the clutch El, which causes the reversalof the motion of shaft D. At the same time, one of the stops c7 hasarrived at the projection g' on check G, which was lifted simultaneouslywith F, and is arrested in its motion. By the same-mentioned lift, oneof the projections, c, on wheel c, which heretofore was stopped by theprojection g on the check G, is now freed from its impediment, and, as aconsequence, shaft D is driven to the right, whereby one oscillation isfinished. Y

Having thus clearly and fully described the construction and operationof my machine,

1. The sliding clutch F, in connection with the pinions d d', clutchesEl E2, check-G, stop-wheels'cfc, rib e, lever I, pins i2 i, and shaft D,constructed and operated in the manner and for the purpose set forth.

2. The connection of the adjustable socket F withv rod l, head L, andset-screw L', supported and moved by shaft D, as aud for the purposedescribed.
